To use backup power:
Move the black jumper to the bottom position to use the backup power port
Move the black jumper to the top position to use the main data port as power
If using more than 20 buttons, it is recommended to use the secondary USB-C port for LED power with a standard 5V 2A cellphone power adapter.

2nd Punch
3rd Punch
4th Punch
Bottom row:
1st Kick
2nd Kick
3rd Kick
4th Kick
 
If using a 6-button layout or Scantron-style layout, unused LED headers can be skipped using the included skip adapters.
XInput Wiring Assignment
 
The XInput layout is fixed on purpose so it follows the fight stick tournament standard used by many modern fighting games, including games like Street Fighter.
 
Most Steam and Windows games work very well with this standard layout.
XInput Button Layout
1P = X
2P = Y
3P = RB
4P = LB
1K = A
2K = B
3K = RT
4K = LT
It is not recommended to change from this layout because the color profile generator will not match if the button order is changed.
For special panels, such as a 2-button layout or Mortal Kombat layout, you can physically wire the buttons in the order you need.
 
Keyboard mode inputs can be adjusted as you wish.
XInput mode is not adjustable by design.
 
Benefits Compared to Other Encoders
Perfect player order in XInput mode
XInput and keyboard keys can work at the same time
Ideal for arcade cabinet builds
Controls up to 52 buttons plus LEDs from one board
Uses only one USB-C cable for most setups
Saves space and wiring cost
Easy upgrade for existing cabinets
Works with bare wire or harness options
No extra plugins required
No background software required
No complicated mapping or programming
Simple GUI profile creation instead of editing text files
Keyboard mode prevents game controllers from being detected by the PC
Ideal for light guns, wheels, flight sticks, wireless controllers, or third-party controllers that need to become Player 1
 
Important Windows XInput Note
Windows officially supports a maximum of 4 XInput devices.
Using a Bluetooth Xbox controller at the same time may cause conflicts because of Windows driver limitations.
If you want to use wireless controllers, change the board to Keyboard mode by holding:
Back + Start + Kick 1 for 5 seconds
When the wireless controller is disconnected, you can return to XInput mode by holding:
Back + Start + Punch 1 for 5 seconds
 
To use the recovery tool, hold Back + Start while plugging in the USB cable.
Happy Retro Gaming!
